TessErrorLoadEngine, UiPath.Vision.Host has stopped working

Hi all,
I installed Uipath Studio on my Mac and it runs on a Virtual Machine done with parallels 12 with Windows 7 Professional.

When I try to use OCR I continue to receive the following error:

Main has thrown an exception
Message: Error performing OCR: TessErrorLoadEngine
Source: Google OCR
Exception Type: Exception

And immediately after I got that

Uipath.Vision.Host has stopped working

Moreover I do not see in the option Microsoft OCR Engine.

For test, I also installed Uipath on another Mac with an older version of Parallels and Windows 7 Ultimate and there everything is working perfectly.

Any idea on how to fix this issue? Please find also below the server stack trace.

Thanks for your help

“TessErrorLoadEngine” occured on my PC (WIndows 10, 64bit) too.
But I haven’t got “Uipath.Vision.Host has stopped working” error and
I see “Microsoft OCR Engine” on Activities list.
Plase help me.
